Udit99 made a no-frills website called VisaMapper, to limit the pain of Visa research headache. In VisaMapper, visitors can select their nationality from a drop-down menu and right away see, on a color-coded world map, which countries require a visa for them to visit and which don’t. This might be the most amazing thing a Reddit user has done in a while. Tell VisaMapper you’re of Swedish citizenship, for example, and watch loads of nations on the map turn to happy shades of green. This color means you won’t need a visa to visit them.

For example, tell VisaMapper you are of Swedish citizenship, and watch loads of nations on the map turn to happy shades of green. This color means you will not need a visa to visit them. And if a visa is required prior to arrival then goes instantly maroon. So green means no visa, maroon means you will need one.

Few countries are missing from the site, and one should double-check its data with the State Department prior to traveling, but the map is nevertheless addicting and instructive. Play around with it to see what travel is like as a citizen of different countries.
